摘要：

附加质量法是粗粒料密度测试的无损检测方法之一，介绍了附加质量法的基本原理和理论模型，并成功应用于昆明新机场粗粒料填筑的压实密度检测。试验结果表明：（1）附加质量法检测得到的地基刚度与灌水法检测得到的干密度呈线性相关，相关系数为0.81，利用率定试验得到的经验关系计算得到的干密度与验证试验的相对误差在-1.78%～1.75%之间，其检测精度能够满足施工检测精度检测要求，并给出了昆明新机场粗粒料压实密度检测的经验关系式；（2）附加质量法具有操作简单、检测速度快捷、被检测粗粒料无损伤等优点，是一项很有发展前景的无损检测技术。

Abstract:

The additive mass method is one of nondestructive methods used for the compacted density testing of coarse materials. The theory of it is introduced; then its theoretical model is introduced too. The additive mass method is successfully used in the compacted density testing in Kunming new airport. The result shows: (1) the linear interrelation between foundation stiffness tested by the additive mass method and density tested by the water replacement method is about 0.81, relative error between the density from demonstration test and density from empirical relationship of calibration test is about -1.78%—1.75%, which shows that the testing accuracy of the additive mass method satisfied the requirement of construction testing accuracy; then the empirical relationship of compacted density of coarse material in Kunming new airport is given; (2) because of its advantages, such as convenient operation, fast testing and nondestructive for tested coarse material, etc., the additive mass method is one of the most prospective nondestructive methods.

Key words: coarse material, compacted density, nondestructive testing technique, additive mass method
